The government said on Friday that 1,995 children were separated from 1,940 adults at the U.S.-Mexico border between April 19 and May 31, as the Trump administration implements stricter border enforcement policies.

The administration also will place on hold a program that allows for family reunification for some refugees resettled in the United States, according to a Trump administration memo seen by Reuters and sent to Congress on Tuesday. The resettling of so-called following-to-join refugees will resume, according to the memo, once screening "enhancements have been implemented."
